The rules for calculating Easter are rather complex. Easter Day falls on the first Sunday after the first full moon that falls on or after March 21, but the “full moon” referred to is not the real moon but a theoretical moon that doesn’t quite match the one in the sky. In 1928, the British House of Commons agreed to a bill fixing the date of Easter, subject to agreement by various Christian churches. Efforts to secure that agreement, however, have been going on ever since.
The name of “Easter” is generally believed to be derived from Eostre, the pagan goddess of dawn, though recent research suggests that Eostre may not have been a goddess at all but the name of a season, and the “goddess” was only a mistranslation by the Venerable Bede in the eighth century.
Easter Island in the Pacific was discovered by the Dutch sailor Jacob Roggeveen on Easter Day 1722.
The plant that we now call an Easter Lily was discovered in 1777 in the Ryukyu Islands of Japan. Interestingly, though, the white lily is mentioned in the Bible and has been a symbol of Christianity since its beginnings.

If you’ve been gifted with an Easter lily and you have pets, you should know that the plant is poisonous. Though the plant presents a high rate of toxicity to cats who ingest it, many pet owners are not aware of the dangers posed by it. There are no documented cases of poisoning by Easter lily in dogs, but there is a definite possibility of effects such as gastrointestinal upset or internal obstruction if your dog eats a large amount of this plant. Most cases of ingestion of the Easter lily by canines will mean mild gastrointestinal upset simply because the digestive systems of dogs are not used to processing plant material, especially in large quantities. While considered as lethal to cats, the Easter lily is not toxic to dogs but this does not mean your canine companion should have free rein to ingest this plant. The Easter lily is known to be extremely toxic to the feline species. While this flower is not documented as poisonous to dogs, ingestion of the flower in large quantities may lead to digestive discomfort.
